The benefit of frequently updating to new versions of foreign code
is that when you don't, you will have a really hard time updating
later when you _do_ want some new feature. If you do update, you
also get bug fixes for bugs that you do not (yet!) run into yourself,
etc. It saves a lot of work. Frequent back-merges are easy, trying
to do one after a few years can often be almost impossible.
If you don't keep track of foreign code, you'll find yourself
maintaining a fork of that foreign code, at which point it might
have been better to just write the whole code from scratch.
